A magnetoelectric machine can be referred to by several synonyms, including the magnetostrictive generator, magnetostrictive transducer, and magneto-electro-mechanical converter. It is a device that converts mechanical energy into electrical energy, or vice versa, by exploiting the coupling between magnetic and electric fields. Other related terms include piezomagnetic or magnetostrictive materials, both of which are used to achieve the magnetoelectric coupling in these machines. The magnetoelectric machine finds applications in energy harvesting, sensors, actuators, and transducers, with particular significance in the fields of renewable energy and non-invasive medical imaging. It is an exciting area of research and innovation with ongoing efforts to improve efficiency and durability of these devices.
